It is at about 40 weeks on the New York Times best-seller list. It has sold more than five million copies. It is a novel entitled The Shack by a first-time author, originally self-published with the help of two pastors that raised just $300 for a marketing budget.
Summary by Jenn Cavanaugh, reviewer for Youth Worker Journal: "God sets aside a weekend to lead Mack, a man overwhelmed by a family tragedy, into a more trusting relationship with Herself. Yes, Herself. All three persons of the Trinity take turns reconstructing Mack's notions of God. His image of God as a white man is among the first challenged. Discourses on freewill and theodicy transpire over meals and yard work. Putting words in God's mouth is a risky business, and the lapses into trite Sunday School formulas are precariously balanced by more winsome moments. The result is an extremely human rendition of God but a generally orthodox and thought-provoking one. [It] serves as a rendezvous point for any whose pain has obscured a sense of the presence, or goodness, of God-with-us."
It is important to keep this phenomena in perspective. The circulation of this volume is still way below that of The Da Vinci Code, although, in fairness, that book had an established author and a major publisher behind it. And there are evidently no published demographics on who is purchasing The Shack. Nonetheless, Why do you think this book has become so popular? Is it being read by people outside of church circles?
